I'm stuck with 3 things:1)Don't understand,how to put the chain into the motor(where the little sprocket is).By the way-what sprocket is not moving at all.2)The rear sprocket looks kinda wobbling.3)The clutch arm,if i got it right,is suppose to move inside(towards to the right side of engine).Mine is moving out.Sorry,maybe i'm askin' some stupid questions,but that is a first mechanical job in my life,which i doin' myself.Thanks for supporting!
